GE8M/1A

Clock Pulse Generator. Generates TTL or balanced clock

pulses at a frequency of 864 x line frequency (13. 5MHz).

Also produces Mixed syncs, line trigger, field trigger (TTL

levels), and Line Start and Field Start pulses related to

clocks. Requires an input of composite video or syncs.

Power requirements :t12V, +5V -5V (if balanced O/p used).

CH1/64J. DD 1981. DDMI 1.252(82). DDHB 1.165(82).

Clock Pulse Generator. Provides a 4 FSC logic clock

pulses. Used in conjunction with GE2/627A to form a

digital phase lock system. The unit forms part of the 68

Mbits sub-Nyquist PAL system. CH1/64A. DD 1982. DDHB

1.174(83). DDHB 1.194(85).

Digital TV Clock Generator. Provides 27 MHz pulses clock

locked to an input of mixed syncs. Also produces digital

line, field and mixed blanking and Timing Reference

signals. Power requirements :t5V, :t12V. CH1/64A. DD 1983.

DDMI 1.262(85). DDHB 1.194(85). EDI 10516(1) DEC 85.

Subcarrier Phase Generator. When driven by a 13.5 MHz

clock, this unit will generate a digital representation of

the phase of PAL colour subcarrier at each sample point. A

control input allows the line by line "frequency" to be

changed to facilate burst locking. Power requirements

(approximately) +5 V, 2 A, -5 V, 0.1 A. 4 U unsupported

PCB, with 57-way double-sided edge connector. Parent
