The f\/2 pre-scalar output is further divided by 1, 2, 4, or 8 for the Φ1 bank via D0 and D1 of a two-bit DIP switch, providing a maximum ratio of 16. It is divided by 2, 4, 8 or 16 for the Φ2 bank via D2 and D3 of a second two-bit DIP switch, providing a maximum ratio of 32. All outputs are synchronous with the input frequency and are square waves (50% duty cycle) suitable for driving long lines terminated into 50 Ω\/-2 V or AC-coupled 50 Ω loads.\u003c\/p\u003e\n\u003cp\u003eThe PRL-257-2 is ideal for applications where a high frequency divider or pre-scalar is needed for triggering or down-sampling. The two phases of output enable applications requiring two different ratios from a common reference frequency, and the 1:2 fanout feature enables system synchronization and monitoring\/triggering applications from a single reference clock source. Applications for the PRL-257-2 include data acquisition, test, measurement, R\u0026amp;D, and system integration.\u003c\/p\u003e\n\u003cp\u003eThe unit includes an AC adapter for ready-to-use convenience on the bench or in a system.

It is capable of running at input frequencies in excess of 12 GHz.\u003c\/p\u003e\n\u003cp\u003eIt has a common divide-by-8 pre-scalar front end followed by two banks of independent manually programmable dividers, Φ1and Φ2. The f\/8 pre-scalar output is further divided by 1, 2, 4, or 8 for the Φ1 bank via D0 and D1 of a two-bit DIP switch, providing a maximum ratio of 64. It is divided by 2, 4, 8 or 16 for the Φ2 bank via D2 and D3 of a second two-bit DIP switch, providing a maximum ratio of 128. All outputs are synchronous with the input frequency and are square waves (50% duty cycle) suitable for driving long lines terminated into 50 Ω\/-2 V or AC-coupled 50 Ω loads.\u003c\/p\u003e\n\u003cp\u003eThe PRL-257-8 is ideal for applications where a high frequency divider or pre-scalar is needed for triggering or down-sampling. The two phases of output enable applications requiring two different ratios from a common reference frequency, and the 1:2 fanout feature enables system synchronization and monitoring\/triggering applications from a single reference clock source. Applications for the PRL-257-8 include data acquisition, test, measurement, R\u0026amp;D, and system integration.\u003c\/p\u003e\n\u003cp\u003eThe unit includes an AC adapter for ready-to-use convenience on the bench or in a system.

a [specified] bandwidth up to 12GHz, and my measurements show that its actual bandwidth goes out to 14GHz.  I thought that was very good margin.  But what really impressed me was the jitter performance.  I fed in a clock source with 170fs one sigma RJ, and the clock divider puts out a divided down clock with 770fs one sigma RJ.  That is surprisingly good for a small device with such high bandwidth.  Usually you would expect this kind of performance from a device weighing 40 lb and takes up a whole lot of bench top space, but this clock divider is small enough to fit in your

It is capable of running at input clock frequencies in excess of 1 GHz and outputting divided TTL and NECL clock signals. The input frequency f is first divided down to f\/n, where 2 ≤ n ≤ 256, via D1-D8 of a ten-bit DIP switch. The f\/n signal is further divided by 1, 2, 4, or 8 for the Φ1 NECL and TTL outputs via D9 and D10, for a maximum ratio of 2048, and by 2, 4, 8 or 16 for the Φ2 NECL output via D11 and D12 of a second two-bit DIP switch, for a maximum ratio of 4096.\u003c\/p\u003e\n\u003cp\u003eAll outputs are synchronous with the input frequency and are square waves (50% duty cycle), except for Φ1 output when the final divisor is set to 1 (D9-D10=00). When the final divisor is set to 1 the output positive pulse width is equal to the input pulse period. All outputs are complementary and will drive long lines. TTL outputs are back-matched and will drive terminated or unterminated loads. NECL outputs can drive 50 Ω loads terminated into -2 V or AC-coupled 50 Ω loads.\u003c\/p\u003e\n\u003cp\u003eA complementary NECL input is logically ORed with a TTL\/Small Signal input, enabling the unit to accept TTL input, small signals (≥40 mV), single-ended or differential NECL input,  AC-coupled sinewave or other logic inputs. There is an Input Mode switch and a Threshold Voltage switch. For differential NECL inputs, both SMAs are used with both switches up. For single-ended NECL input the lower SMA is used with Input switch down and the Threshold switch up. For AC-coupled input either SMA can be used with both switches up. For TTL input the BNC input is used with the Input switch down and the Threshold switch up. For small signals the BNC input is used with both switches down.\u003c\/p\u003e\n\u003cp\u003eThe NECL inputs are internally terminated to 50 Ω\/-2 V in the differential input mode, and the inverted input to 62 Ω\/-1.3 V in the single-ended input mode. The BNC input has a ground-referenced 50 Ω termination, and the minimum signal required is only 0.75 V for TTL (switch up) or 40 mV for small signals (switch down):\u003c\/p\u003e\n\u003ctable class=\"datatable\" border=\"1\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth bgcolor=\"#CCCCCC\"\u003eDesired Input\u003c\/th\u003e\n\u003cth bgcolor=\"#CCCCCC\"\u003eConnector(s)\u003c\/th\u003e\n\u003cth bgcolor=\"#CCCCCC\"\u003eInput Mode Switch\u003c\/th\u003e\n\u003cth bgcolor=\"#CCCCCC\"\u003eThreshold Switch\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth align=\"left\" bgcolor=\"#CCCCCC\"\u003eDifferential NECL\u003c\/th\u003e\n\u003ctd align=\"center\"\u003eBoth SMAs\u003c\/td\u003e\n\u003ctd align=\"center\"\u003eUp\u003c\/td\u003e\n\u003ctd align=\"center\"\u003eUp\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth align=\"left\" bgcolor=\"#CCCCCC\"\u003eSingle-ended NECL\u003c\/th\u003e\n\u003ctd align=\"center\"\u003eLower SMA\u003c\/td\u003e\n\u003ctd align=\"center\"\u003eDown\u003c\/td\u003e\n\u003ctd align=\"center\"\u003eUp\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth align=\"left\" bgcolor=\"#CCCCCC\"\u003eAC-coupled\u003c\/th\u003e\n\u003ctd align=\"center\"\u003eEither SMA\u003c\/td\u003e\n\u003ctd align=\"center\"\u003eUp\u003c\/td\u003e\n\u003ctd align=\"center\"\u003eUp\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth align=\"left\" bgcolor=\"#CCCCCC\"\u003eTTL\u003c\/th\u003e\n\u003ctd align=\"center\"\u003eBNC\u003c\/td\u003e\n\u003ctd align=\"center\"\u003eDown\u003c\/td\u003e\n\u003ctd align=\"center\"\u003eUp\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth align=\"left\" bgcolor=\"#CCCCCC\"\u003eSmall Signals\u003c\/th\u003e\n\u003ctd align=\"center\"\u003eBNC\u003c\/td\u003e\n\u003ctd align=\"center\"\u003eDown\u003c\/td\u003e\n\u003ctd align=\"center\"\u003eDown\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eThe PRL-260BNT is ideal for applications where a frequency divider or prescalar is needed for triggering or down-sampling, and the multiple logic inputs and outputs make it extremely useful in mixed-logic environments.

The floating 100 Ω inputs are designed for interfacing with differential signals within the common mode range of -2.4 V to +4.0 V. Therefore, they are compatible with LVDS, RS422, LVPECL, LVTTL\/CMOS, NECL, PECL or TTL differential input signals. The PRL-425N has complementary NECL outputs for driving 50 Ω loads terminated to -2 V, floating 100 Ω loads or AC-coupled 50 Ω loads. It is also a long line driver, designed specifically for use with high speed data communications applications. Functional block diagrams of these devices are shown in Fig. 1 and Fig. 2.
