IDT9173B

VIDEO GENLOCK PLL

CLOCK SYNTHESIZER

IDT™ VIDEO GENLOCK PLL

IDT9173B

REV B 111209

DC Electrical Characteristics

Unless stated otherwise, VDD = 5 V ±5%, Ambient Temperature 0 to +70

° C

Notes:

1. Duty cycle measured at 1.4 V.

2. Input Reference Frequency = 25 kHz, Output Frequency = 25 MHz. Jitter measured between adjacent vertical

pixels.

3. CLK1 frequency applies for FS = 0. For FS = 1 condition, divide allowable CLK1 range by the factor of 4.
